How to correct a form 15h that has been submitted already?

I have submitted for 15H this year as my income was below the 2.5L limit. However, it was recently pointed out to me that I might have made an error in my calculations. Basically, I did not incorporate "ACCRUED INTEREST"m in my calculations. My net income in Form 15H is shown as 2.43L..however, with the ACCRUED interest, it is likely to jump to 2.56L.

I am uncertain how to handle this. Is there still an option for me to do a correction / rectification of my 15H? I am concerned that ITO might flag me for incorrect submiission subject to penal consequences.

i request the forum members to kindly guide me here. You help is much appreciated.

Thank you.
